Greenies, I've stuck by you for so long and made so many excuses for the bad service, now I'll go to mojo bones or poppas. Carrie L. and 2 others voted for this review Useful 3
Functions[edit] A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
A function definition consists of a declaration, plus the body, which is all the code between the curly braces. A function declaration followed by a semicolon may appear in multiple places in a program. It must appear prior to any calls to that function in each translation unit.
